X + 3y = 9
3x - 3y = -13
---------------------  add the equations
4x  = -4
divide both sides by 4
x = -1

plug -1 back into either equation and solve for 'y'.
x + 3y = 9
-1 + 3y = 9
add 1 to both sides
3y = 10
divide both sides by 3
y = 10/3 or y = 3 1/3

(-1, 10/3), OR (-1, 3 1/3)

X + 3y = 9
3x - 3y = -13
--------------add
4x = - 4
x = -4/4
x = -1

x + 3y = 9
-1 + 3y = 9
3y = 9 + 1
3y = 10
y = 10/3

solution (-1,10/3)

How can you find approximations (estimations) of square roots?
Luda [366]
To find approximations of square roots, you should find the nearest prefect square. For example if your looking to approximate the square rot of 10, the closest perfect square is 9 and the square root of that is three. Thus, you can say that the square root is about 3. Hope this helps and please mark brainiest. :D

The point P(6, –1) is translated according to the rule (x, y) → (x – 5, y – 2).
monitta

The <em>resulting</em> point by considering that P(x, y) = (6, - 1) and P'(x, y) = P(x, y) + (- 5, - 2) is equal to the coordinates P'(x, y) = (1, - 3). (Right choice: C)

<h3>How to determined a resulting point by translation</h3>

In this question we need to determine the new location of a point by using a <em>translation</em> formula. Translations are rigid transformations in which a point is translated on a <em>Cartesian</em> plane. We have the following formula:

P'(x, y) = P(x, y) + (- 5, - 2)     (1)

Where:

  • P(x, y) - Original point
  • P'(x, y) - Resulting point

If we know that P(x, y) = (6, - 1), then the resulting point is:

P'(x, y) = (6, - 1) + (- 5, - 2)

P'(x, y) = (1, - 3)

The <em>resulting</em> point by considering that P(x, y) = (6, - 1) and P'(x, y) = P(x, y) + (- 5, - 2) is equal to the coordinates P'(x, y) = (1, - 3). (Right choice: C)
